Diablo by Cymatics is a very useful plugin. Mainly used to add a little something extra to your drums, this plugin can be used on just about anything. Using Diablo on an Acoustic guitar can give it more character and make it feel alive. Synths, no problem they have presets for them too. Overall, a great plugin. I would recommend learning Diablo's features as it can do much more than advertised.
